I just bought a new video card for my computer. I want to refurbish my old card for resale. I had bought some blue thermal pad material from eBay that I use on laptop video chips but for my old video card I want to make sure I use pads that will conduct heat transfer very well without breaking the bank.

My old card is a reference EVGA GeForce GTX 680 FTW. It has 4 gigs of ram and only one fan. I disassembled the card and the thermal pads they use are gray. This is the first time I've seen gray pads. I started looking around and saw there are different strengths. I've seen pads with 5.0W/mK, on up to 11. The 11's are very expensive.

My question is: Since this is a reference card with one fan, will it be safe with thermal pads rated at 5.0W/mK or must I go higher? I wouldn't want someone to buy it only to have it overheat on them.

Your padding is likely better than anything they would have ever used. Their motto is going to be "the cheapest possible to prevent an RMA"

5w/m K is honestly plenty. I'd be more worried about varying thickness and preventing any air gaps.
Cover all the mosfets, VRMs, and DIMMs while you're at it.

I did this with my EVGA GTX 1080 SC using Arctic's thermal pads which are rated for 6w/m K
